BOBBIN-SUPIPOBT.

ToaZZ whom itmay concern:

Be it known that I, GEORGE R. PLorr, a citizen of the United States, residing at Hillsbor'o, in the county of Orange and State of North Carolina, have invented certain new and useful Improvements in Bobbin-Supports, of which the following is a specification. I i I This invention relates to filling-changing motions for looms and more especially to a novel and improved bobbin support foremployment in connection with a filling-'chang ing motion such as is employed in. the wellknown Northrop loom, one of the primary objects of the invention being to provide means for supporting a bobbin which is inposition to be delivered from the hopper of the motion into the shuttle andto provide for such delivery without likelihood of injury to the boX or shuttle or imposing any undue wear upon the bobbin.

, bobbin which is in turn in position to be de-* Another object of the invention is to provide means for yieldably supporting. the heel or butt of a bobbin while the bobbin is yet within the hopper of the filling-changing motion and which means, while securely supporting the bobbin prior to transference, will be adapted to readily yield uponaction of the transferrer in placing the bobbin within the shuttle.

Another object of the invention is to so construct the device that the same will operate automatically and smoothly and will not be liable to become caught or disar-- ranged but will at all times becapable of operating in a proper and eflicient manner.

In the accompanying drawings:

application, and in the drawings there has been illustrated so much of such a loom as is necessary to disclose the invention. Thus in the drawings there is illustrated the hopper of such a loom comprising the inner and outer headswhi'ch are indicated respectively by the numerals land 2 and between which the bobbins are supported, the bobbins being indicated by [the numeral3 and V Specification of lietters iatentr Patented Ang. 16, 1921.

each having the usual head a which is seated within a recess 5 formed in thegperiph eral portion of the face of the head 1', and the usual nose 6 which is engaged by'a spring retaining element 7 upon the head 2. The headl is provided with a series of the recesses 5, and likewise the head2 is providedwith a series of thespring-retaining elements 7 so that a considerable number of filled bobbinsmay be supported between these heads comprising the hopper of the In order that the heels4 of the bobbin may beretained within the recesses 5,the head 1is' rotatably disposedwithin a circular frame having a projecting flange 8 which closes the open sides of the recesses 5, these recesses opening through the periphery of the head 1. fiowever this flange S is interrupted at its lower side as indicated by the nul'ueral 9 so as to. Provide a. throat 10 flanked by an inclined guide 11, it being understood that as usual the bobbins are to be successively discharged or delivered from the hopper through the throat 10 and guided by the guides 11 into the shuttle which is indicatedb'y the numeral 12,

the delivery of a filled bobbin into the shutthrough a chute 13 into the usual receptacle I 14 provided for receiving the discharged bobbins. The delivery of a filled bobbin through'the throat 10 and into the shuttle 12 is effected by the usual transferrer 15 tion 16, the end of thetransferrer arm engaging the heel of a bobbin whichis to be having the usual transferrer fork connec- 15, and the transferrer carries the usual delivered, and the fork engaging the nose of such a bobbin. The transferrer 15 is actuated in the usual manner through the 00- bow 19 for coaction with the ratchet 20 upon the head 1 of the hopper so that after the transferrer 15 and its fork has been swung downwardly to deliver a filled bobbin into the shuttle 12, and the transferrer is restored to normal position through the medium of the usual spring 21, the hopper will be rotated at part of a revolution to bring into delivery position" another filled bobbin.

The device embodying the invention C0111- prises a pintle 22 which is reduced and threaded at one end as at 23 for the application of a nut 2&, this end of the pintle being fitted through a portion of the frame of the loom as shown in Fig. 2 of the drawing and the nut being applied and tightened thereon to secure the pintle in place. Mounted for swinging movement uponand about theipintle 22 is a supporting member which is indicated in general by the numeral 25, this member comprising a sleeve 26 which rotatably fits the pintle 22, and a fiat pref erably rectangular body 27 which extends radially with relation to the axis of the sleeve. A coil spring 28 is fitted onto the portion of the pintle 22 which projects beyond one end of the sleeve 26 of the supporting member, and one end of this spring is engaged as at 29 about a stud upon the said end of the pintle. The other end portion of the spring is extended beneath the body 27 near its juncture with the sleeve 2-6 and is hooked as at 30 to engage about one lateral edge of the body andin a notch formed in the said edge.

The device is so positioned that the body 27' of the supporting member will be yieldably supported by the spring 28 in position bearing against the under side of the heel of the bobbin which is in position for delivery to the shuttle 12, as clearly shown in Figs. 1 and 2 of the drawings, and it will be understood that .upon operation of the ansferrer 15 and its fork to deliver the filled bobbin, the bobbin in passing into the threat 10, will ride past the end of the body :27 oi the supporting member, depressing the same against the tension of the spring 28, this spring serving to immediately return th supporting member to its normal posltion after the heel of the bobbin has passed the same and so that. when another bobbin is brought to delivery position its heel will be supported by the said member. It will be evident that while the supporting member firmly holds the heel of a bobbin which is in delivery position, in its respective recess in the head 1 of the hopper, the device does not in any way interfere with the proper delivery of the filled bobbin to the shuttle. It will also be evident that, inasmuch as it is upon the return movement of the transferrer 15 that the hopper is rotated to bring the next filled bobbin into, delivery position, and all of the bobbins prior to reaching this position are supported bythe flange 8, the supporting member 25 will have been returned to its normal or supporting position across the throat 10 prior to such rotative movement of the hopper and will therefore be in a position to receive and sup port the heel of the bobbin next delivered as the heel of the said bobbin rides off from th end of the flange 8.

Having thus described the invention, what is claimed as new is: I

A device for the purpose stated comprising a pintle, a bobbin supporting member comprising a plate formedbetween its ends with a sleeve pivotally fitting the pintle and having its portions beyond the sleeve in mu tual fiat contact to provide a supporting leaf, and a spring coiled about the pintle and having operative connection with the leaf to yieldably support the same.

In testimony whereof I affix my signature.
